What are pipe flanges, and how do they work?

langes are the second most used joining method after welding by offering a reliable way to connect piping systems with various equipment, valves, and other components. You can choose stainless steel flange bolts manufacturers in India. Flanges add flexibility when servicing piping systems, allowing for easier disassembly and better access to system components.

• Flanges for pipes
• Gasket
• Bolting

In most cases, specific gaskets and hardware materials are made from the same materials as the piping components you want to connect.

 

Stainless steel flanges from Copper nickel pipe suppliers are among the most common. However, flanges are available in a wide range of materials, so it is essential to match them to your needs. Depending on the application, other common flange materials include Monel, Inconel, Chrome Moly, and many more. The best option for your needs will depend on the system in which you intend to use the flange and your specific needs.

 

 

Common types and characteristics of flanges

 

Flanges are not a one-size-fits-all type of solution. Aside from size, matching the ideal flange design to the piping system and intended use will help ensure reliable operation, long life, and an optimal price. Super Duplex Flanges manufacturers in India provides various flanges and bolts for industrial use.

 

Threaded flange

 

Also known as a screwed flange, this style has a thread inside the flange hole that fits the corresponding male thread on the pipe or fitting. Match the thread to the tubes you want to connect.

 

Socket-weld weld flange

 

Ideal for smaller pipe diameters in low temperature and low-pressure scenarios, weld flanges feature a connection where you place the pipe into the flange and then secure the relationship with a single multi-pass fillet weld. This makes this style easier to install than other types of the welded flange, avoiding the limitations associated with threaded ends.

 

Welding neck flange

 

Their integrity, performance in systems with multiple repeating curves, and the ability to use them in high-pressure, high-temperature systems make them a leading choice for process piping.

 

Special flanges

 

A range of additional specialty flange types is available to suit a wide range of uses and environments. Other options include nipple flanges, weld flanges, expandable flanges, orifice, long weld neck, and reduction flanges.

 

Making the connection: flange face types

 

When considering the ideal flange from Super Duplex Plate Suppliers for your piping system, the design is just the beginning. Face types are another feature that will have a major impact on the final performance and life of the flanges. The face types determine the gaskets needed to install the flange and the characteristics of the seal created.

 

Flat Face (FF): As the name suggests, flat face flanges feature a flat, uniform surface combined with a full face gasket that contacts most of the flange surface.

 

The choice between options is important as they will determine the optimum seal for a reliable seal.

 

In general, smooth faces work best with metal seals, while serrated faces help create stronger seals with soft material seals.
